Public bug reported:
Ubuntu 26.04, Kernel 7.0.0-38-generic, Sony VAIO VPCEH2Z1E,
NVIDIA GF119M (GeForce 410M), Treiber nouveau.
HDMI-Ton funktioniert nicht. Der HDMI-Ausgang ist an der NVIDIA-GPU,
der Monitor wird erkannt und zeigt ein Bild (connected/enabled).
Das EDID des Monitors meldet Audio (Basic audio support, Audio Data Block).
Trotzdem:
- /proc/asound/card1/eld#0.0: monitor_present 0, eld_valid 0
- Codec Node 0x05: Pin-ctls 0x00, auch waehrend der Wiedergabe
- PipeWire-Sink vorhanden, Pegel schlaegt aus, am Monitor kommt kein Ton
Bereits probiert, ohne Wirkung: Kernel 6.8.0-147 (gleiches Verhalten),
nouveau.runpm=0, nouveau.config=NvAudio=1, Unbind/Bind von 0000:01:00.1,
Monitor aus-/einschalten in den Anzeigeeinstellungen.
Unter einer frueheren Ubuntu-Version funktionierte der Ton.
Ausgaben (ELD, EDID, dmesg) siehe Anhang.
